Problem with utlrp?

I looked at how you could use utlrp to compile invalid objects in an earlier post: 

SQL> @utlrp
 
TIMESTAMP
----------------------------------------------------------------------------------------------------
COMP_TIMESTAMP UTLRP_BGN  2013-02-14 16:09:12
 
DOC>   The following PL/SQL block invokes UTL_RECOMP to recompile invalid
DOC>   objects in the database. Recompilation time is proportional to the
DOC>   number of invalid objects in the database, so this command may take
DOC>   a long time to execute on a database with a large number of invalid
DOC>   objects.
DOC>
DOC>   Use the following queries to track recompilation progress:
DOC>
DOC>   1. Query returning the number of invalid objects remaining. This
DOC>      number should decrease with time.
DOC>         SELECT COUNT(*) FROM obj$ WHERE status IN (4, 5, 6);
DOC>
DOC>   2. Query returning the number of objects compiled so far. This number
DOC>      should increase with time.
DOC>         SELECT COUNT(*) FROM UTL_RECOMP_COMPILED;
DOC>
DOC>   This script automatically chooses serial or parallel recompilation
DOC>   based on the number of CPUs available (parameter cpu_count) multiplied
DOC>   by the number of threads per CPU (parameter parallel_threads_per_cpu).
DOC>   On RAC, this number is added across all RAC nodes.
DOC>
DOC>   UTL_RECOMP uses DBMS_SCHEDULER to create jobs for parallel
DOC>   recompilation. Jobs are created without instance affinity so that they
DOC>   can migrate across RAC nodes. Use the following queries to verify
DOC>   whether UTL_RECOMP jobs are being created and run correctly:
DOC>
DOC>   1. Query showing jobs created by UTL_RECOMP
DOC>         SELECT job_name FROM dba_scheduler_jobs
DOC>            WHERE job_name like 'UTL_RECOMP_SLAVE_%';
DOC>
DOC>   2. Query showing UTL_RECOMP jobs that are running
DOC>         SELECT job_name FROM dba_scheduler_running_jobs
DOC>            WHERE job_name like 'UTL_RECOMP_SLAVE_%';

However, I recently had a problem with utlrp where it failed to recompile a package body which had been invalidated:
 
SQL> select object_type, status
  2  from dba_objects
  3  where owner = 'JLS'
  4  and object_name = 'PK_JULES'
  5  /
 
OBJECT_TYPE         STATUS
------------------- -------
PACKAGE             VALID
PACKAGE BODY        INVALID

SQL>

When I recompiled it manually, it had no errors. I will update this post once I understand the cause of the problem. In the meantime, if you have any idea what caused this to happen, please let me know:
 
SQL> alter package jls.pk_jules compile
  2  /
 
Package altered.
 
SQL> select object_type, status
  2  from dba_objects
  3  where owner = 'JLS'
  4  and object_name = 'PK_JULES'
  5  /
 
OBJECT_TYPE         STATUS
------------------- -------
PACKAGE             VALID
PACKAGE BODY        VALID
